MACHINE FOR LAS'IING- STITCHDOWN-SHOES.

. Application filed June 15,

Z '0 (all to ho-m it may concern:

Be it known that I, FREDERICK H. PERRY, a citizen of the United States, residing at Beverly,'in the county of Essex and State of Massachusetts, have invented certain 1mprovements in Machines for Lasting Stitchdown-Shoes, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters 011 the drawings indicating like parts in the several figures.

This invention relates to machines for use in the manufacture of boots and shoes of the stitch-down or Veldtschoen type and particularly to a machine for progressively folding the margin of upper material over the projecting edge of the sole or innersole of a stitch-down shoe. 7

The marked increase in the cost of upper leather has caused more attention to be paid of late to the use of canvas and other fabrics for shoe uppers as substitutes for leather, particularly in the more moderate priced shoes. The simplicity and cheapness of the stitch-down type of shoe have attracted manufacturers to this type particularly in connection with the use of fabric uppers,- hut a difficulty has been encountered in that the outturned margin of a fabric upper can not be satisfactorily trimmed and finished to correspond with the edge of the sole and welt (when a welt is used), the fabric havin g a tendency to ravel and produce a ragged layer on the edge face of the sole in contrast to the leather or rubber of which the sole is composed.

An object of this invention is to provide a machine for so handling the outwardly extending margin of the upper material of a stitch-down shoe as to avoid trimming off the material and to form a finished edge of neat appearance and one such that the use of a welt in attaching the outsole is unnecessary.

Features of the invention consist in means against which the shoe is rested and acting to tuck the margin of the upper into the angle between the side of the last and the projecting margin of the sole and to fold the upper material over upon the edge face of the sole. prises a single tool having three acting faces, one of which works the upper against the side face of the last, another which presses Specification of Letters Patent.

As shown herein, this means com- Patented Dec. 28, 1920.

the upper against the top face of the projecting margin offthe sole, and the third which lays the upper against the edge face of the sole. The contacting faces of the upper and sole may either or both be coated with cement which will hold the upper in the position in which it is placed by the acting faces mentioned. Preferably and as shown herein, the tool having the acting faces is given a vibratory movement which causes the upper to be beaten against the side of the last and against the edge face of the sole and to be rubbed against the top face of the projecting margin of the sole. This is advantageous in that the upper is worked closely into the anglebetween the side of the last and the projecting margin of the sole; the portion of upper overlying the top face of the sole margin is rubbed to remove wrinkles and to cause the cement firmly to adhere, and the portion of upper extending across the edge face of the sole is beaten against the edge face and conformed to the angle between the top face and edge face of the sole.

A further feature of the invention consists in means for working the margin of the upper which extends beyond the edge face of the sole against the margin of the sole bottom. Preferably, and as shown herein, the working means consists of a yield ing wiper which is given movement in a closed path, part of which intersects the sole and causes the wiper to move in contact with the upper in a direction from the edge of the sole toward the inner portion of the sole, and to wipe the upper with increasing pres sure from the edge of the sole inwardly. As shown, the path of free movement of the wiper is an elongated closed curve having its longer axis inclined to the plane of the sole, the direction of movement of the wiper when in contact with the sole being from the edge of the sole inwardly of the shoe, and the inclination of the axis causing the yielding wiper when in contact with the sole to wine with increasing pressure as it moves from the edge inwardly. The margin of the upper or the marginal edge of the sole or both are coated with cement to hold the upper in place after being wiped.

Another feature of the invention consists in means for beating the margin of the up-'- per which is wiped against the bottom face of the sole. The beater operates after the upper has been wiped into position, and con sists, as herein shown, of a yielding plunger which is reciprocated in a direction substantially perpendicular to the sole into contact with the wiped upper to insure contact with the upper and sole and firm adhesion of the cement to secure the materials in place. Preferably and as shown, the beater has a component of movement away from the sole edge while in contact with the work to smooth and work inwardly the wiped upper.

These and other features of the invention will appear more fully from the following detailed description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

' thereby In the drawings,

"Figure 1 is a side view of the machine embodying this invention, part of the casing being broken away;

Fig. 2 is a plan view of the machine, the

casing being shown in section;

Fig. 3 is a detail in perspective of the operative parts of the machine and their relation to the work; and

Fig. 4 is a detail plan View, partly in section, of the operative parts of the machine,

Referring to the drawings, the numeral 2 indicates the casing of the head of the machine which is preferably mounted on a column 4. In the casing 2 is journaled a shaft 6 having a pulley 8 to be driven from any convenient source of power. On the shaft 6 are mounted cams and eccentrics from which the movements of the machine parts are derived. A tool 10 is mounted by means of a screw and slot connection 12 on one end of a lever 14 pivoted at 16 to the casing and having adjacent to its other end a cam roll 18 arranged to contact with the edge of a drop cam or precipice 20. The drop of this cam is shown at 22, Fig. 1. Beyond. the roll 18 is an extension 24 of the lever 14 which is connected by a spring 26 to a stationary pin 28 on the casing. The cam 20 depresses the roll 18 once in each revolution of the shaft a ainst the tension of the spring 26 and suddenly releases it, giving a substantially vertical reciprocation tothe tool 10. The tool has three acting faces; one face 30 forces the upper against the side of the last and another face 32 engages the upper in position and forces the upper againstthe edge face of the sole. Still another face 34 of the tool 10 acts upon the upper covering the top face of the projecting margin of the sole to rub it against the margin and acts with the face 32toform an angle in the upper about contact with the upper covered face of the sole margin or flange during its movements which are sufficiently rapid to be called vibratory. Since the face 34 of the tool 10 remains in continuous contact with the shoe flange it is, in effect, a work rest or support and may be described as a work support having a vibratory movement at right angles to the sole edge and also at right angles to the direction of feed of the work, that is, laterally of the projecting flange of the sole. The faces 30, 34 cooperate, of course, to tuck the upper into the angle between the side of the last and the projecting margin of the sole, and the faces 34, 32 cooperate to fold the upper about the top corner of the edge face of the sole while the falce 32 beats it against the edge face of the so e.

A wiper 40 comprises a resilient member bent in the form shown, one end overlying the upper face of the lever 42 and the other end secured by screws 44 to the lower face of the lever. The lever 42 is pivoted between its ends at 43, the outer arm of the lever being the longer, to a link 46 having a fixed pivot 48 at its other end. The inner end of the lever 42 constitutes a strap 49 encircling. an eccentric 50 by which, of course, the inner end of the lever is moved in a circular path having in-and-out and upand-down components. These movements are communicated to the outer end of the lever and are modified by the movable fulcrum on the link 46, downward movements of the inner end of the lever giving upward movements of the wiper and vice versa. The wiper moves in a path having substantially the shape indicated in dotted lines, Fig. 1, and by reason of the fact that the pivot 48 is nearer the eccentric than the wiper, the up-and-down movements of the wiper will be longer than the in-andout movements. The free path of movement is, as shown, substantially an oval having its longer axis inclined to the plane of the sole. It will be noted that the path of the wiper intersects the work along a line beginning substantially at the edge corner of the sole bottom and extending inwardly of the shoe for a distance and then outwardly. When operating the machine, free. movement of the wiper in the path described is interfered with and the wiper contacts with the margin of the upper near the edge corner of the sole bottom and acts upon the sole with increasing pressure as the wiper yields inwardly toward the machine. These wiper movements, being rapidly repeated as the shoe is advanced bythe operator, act to work the upper margin into place against the bottom face of the sole where it is held by the cement coated contacting surfaces. The upper end of the wiper 40 is turned downwardly to form a flange which cooperates with a pin 41 on the lever 42 to prevent reverse bending of the wiper 40.

To insure contact of the materials and firm adhesion of the cement, a beater is provided to beat the upper against the sole. The beater comprises a yielding plunger 60 mounted in the end of an arm 64 and held toward the work by a spring 65, Fig. 4, the plunger being arranged for limited longitudinal movement by a pin and slot connection at 62. The arm 64 is slidably mounted in a rocker 66 having a stud shaft 68 journaled in a lug'7O secured at 72 to the casing. The inner end of the arm carries a strap 74 on an eccentric 76 by which the arm and the beating plunger 60 are reciprocated toward and from the work. Since the pivot 68 and the rocker 66 are arranged adjacent to the work, the vertical component of movement given to the beating plunger is relatively small. As the plunger is advanced into beating contact with the margin of the upper upon the shoe bottom it is given by the eccentric a slight downward movement which aids in stretching the upper away from the edge in conjunction with its beating action, the beater having, therefore, a component of movement inwardly of the shoe while in contact with the upper. As clearly shown in Fig. 2, the work engaging face of the shoe supporting and tucking member 10 is sufliciently wide to support the shoe against the action of both the wiper and the beater.

The shoe materials are prepared for the operation of the machine by securing to the last bottom a sole having its marginal portion projecting beyond the edge of the last and placing an upper, for instance, a canvas or fabric upper, over the last with its marginal portion projecting across the edge face of the sole, the inner face of the upper margin or the top and bottom faces of the projecting sole margin, or both, having been coated with cement. The upper covered sole edge is then presented to the vibrating tool 10 which presses a portion of the upper against the side of the last and into the angle between the side of the last and the projecting margin of the sole, and also folds the upper across the edge face of the sole while the wiper 40 rubs or wipes the adjacent portion of the margin of the upper against the margin of the bottom of the sole. As the shoe is advanced by the operator, the rubbed portion of the upper is immediately engaged by the beater 60 and beaten against the sole which is supported on its opposite face by the tool 10. The beater 60, in cooperation with the tool 10, therefore, beats the upper in contact with both the top and bottom faces of the sole margin to cause the cement firmly to adhere, and at the same time the upper is being beaten against the edge face of the sole and against the side of the last and rubbed against the upper face of the projecting sole margin, respectively, by the three faces 32, 30, 34, of the tool 10. In this manner the upper is worked progressively closely into the angle between the side of the last and the projecting margin of the sole and is caused firmly to adhere to the top, bottom and edge faces of the projecting sole margin.
